Picked up the 2950 from a member on here, which is almost flawless, and picked up the 2510 from a guy at work that did not know how to use it. Speaker was bad, and had a bad audio cap, so I installed a new cap and everything works perfect. Well, except for I bypassed the int speaker and are using an ext speaker. They both look like new almost. And neither of them have been hacked up. Proper channel expanding, no holes drilled, echo boards, etc... I wondered how the 94hp compaired with the 2510 on receive, and transmit audio quality?
